ALFRED H. SMITH, OF NEW YORK, N. Y.

COMPARTMENT FREIGHT CAR.

' Application filed June 9,

. Serial No. 387,517, I have described a new system of freight transportation involving a. series of independent freight compartments placed upon a single our audit is the object of this invention to provide means whereby such compartments may be securely locked on the car, and with this and other objects in View my invention consists of the parts and combination of parts, as will be hereinafter set forth. v

In the drawings:

Figure 1 is a detail end elevation of a freight compartment on a' car showing a locklng means between the car and-compartment.

Figure 2 is a side elevation of two compartments mounted on a car and locked thereon with the locking means shown in Fi re 1.

igure 3 is a top plan view of Figure 2, the compartments being in section.

Figure 4 is a detail vertical sectional View on the line 4-4 Figure 3.

The reference number 1 designates a freight holding compartment, broken away. The construction of this compartment may be of any approved form. At the four bottom corners of each compartment 1. rovide a locking attachment which I will now describe.

One member of the locking attachment comprises a casting 2 which is suitably 'secured to a wall of the compartment by means of rivets 3. A lug 4 extends forwardly from the casting and beyond the end wall of the compartment and is provided with an elongated slot 5, said slot extending vertically. A closed link 6 is loosely mounted in the slot 5, said link being preferably elongated as shown in the drawing whereby it has an extended bearing in the slot 5 of the lug 4, the lug being comparatively wide. The casting 2 is a right angle casting and fits around the corner of the compartment 1 as shown in the drawing. and is provided with a depending foot 7 which functions to elevate the floor of the compartment above the surface upon which the compartment Specification of Letters Patent.

rests, the foot 7 being reinforced by means of the 2 bar 8.

A rectangular hollow post i) is secured at its lower end by means of rivets 11 to the side sllls 12 of the car while the upper ends of the posts pro ect a suitable distance above the floor of the car and are provided with inwardly e tending lugs 13 which project over and re upon the car floor and which are secured by means of bolts.

The inner faces of the lugs 13 are downwardly and inwardly inclined as at 14% which constitute wedging faces which are adapted to be engaged between the wedging faces 15 depending from an arm 16 of the .casting 2. The extreme lower end of the arm 16 is bent rearwardly on the floor line of the car and forms with the foot 7 and the Z'bar 8 an extended bearing for the co partment when placed upon a supporting surface whereby the floor of the oompartinept is elevated above any water that may acoium-ulate on the surface uponiwhich the compartment may be placed.

The post 9 is provided, near its upper end, with an opening 17 through which a loo ing pin 18 is adapted to pass and be posit oned above the loop 6 when the loop is thr-bwn over the ost as shown in the draw ing whereby the cop is prevented from becoming accidentally disengaged from the post. To prevent the loss of the pin 18 1 sesure it by means of a chain 19 which chain is anchored to a suitable support such for instance as one of the bolts.

In the present invention in order to prevent the link 6 from becoming distorted when in unlocked position when the co ipartment is loaded and on a supporting surface I provide the elongated slot 5 whereby the link 'is free to move upwardly in said slot and the upper end of the slot is so positioned relative to the supporting feet of the com partment that the lower end 01"- the link is free to move upwardly beyond the plane having a downwardly and inwardly inclined face constitutin a wedging element, and a casting atta'chet to the lower corner of the compartment having a downwardly and lIl -Wardly inclined face adapted to coact with the said inclined face of the casting on the car, and means lockmgthe compartment to the said. casting on the car.

' 2. The combination with a car, of a series of independent freight compartments detachably mounted on the car, members secured to the lower corners of each compartment and projecting below the floor of the compartment and having an under bevelled face a loop pivotallysecirred .to saidtmembet, a stake secured to theside sills of the car and projecting above the floor of the 7 car, a bevelled lug extending inwardly from said stake on the car floor, said bevelled faces adapted to engage each other when the compartment is on the car; said loop being adapted to engage said stake and means on the stake to 'lock the loop" to the stake.

.3; The combination with a: freight 'car, of a freight compartment detachabljy mounted on the car, a foot secured at eaohlower fco r-,.

ner of the compartment, and projecting be to anchor the compartment to the car.

5. The combination with a. freightcar, of a series of independently detachable compartments on "said car, a series of stakes secared to the side of the car and projecting above the floor of the car, a series of loops mounted on the lower corners of the compartments to swing and move bodily vertically and adapted to engage the stakes to anchor the compartments to the car, and means to lock the loops to the stakes.

ln tes'timony whereof I aflix my signature.

. ALFRED H. SMITH.
